-The selection window lists the parameters of the modules used in the ADAU145x schematic. It allows user to     select the parameters from DM0 or DM1.+**Note:**If the Slave Select is 0 and MP0 is used as chip select, no configuration is required in the register controls. Otherwise particular multipurpose pin should be configured act as the slave select in the register window. (Hardware Configuration -> ICx - ADAU145x Register Controls -> MULTIPURPOSE/ AUXADC)

-The selection window lists the parameters of the modules used in the ADAU144x schematic. It allows user to select the parameters from Coefficient or Nonmodulo data.  +  - Slave Select Channel -> 'Slave Select Channel x' 
 +  - MPx pin mode -> 'Slave Select for Master SPI port' 
 +  - MPx pin function -> 'Multipurpose function'

 +There is some inconsistency between register control and the 'Default chip/Device Address' in the module. The following table shows the mapping between module's parameter and the register control window.
